We stayed at Sutasinee's Apartment for 3 nights.
The apartment was very clean and in a quiet neighborhood. Its a 10-15 minute walk to the next BTS Station. It was well equipped and we had everything we needed. The walls are pretty thin tho, so you can hear your neighbors sometimes etc.
We had a bit trouble finding the Place since its a bit hidden. Our taxi driver was pretty lost and the streets to get there are very narrow. We had to walk through several gates and a big parking lot to find the house.
The Internet connection was a bit annoying too. We had to log into the wifi over and over again several times a day. This could be improved.
